CABLE-GRIP.

SPECIFICATION forming part of Letters Patent No. 320,744, dated June 23, 1885.

Application filed April 11, 1885. (No model.)

To aZZ whom it may concern.-

Be it known that I, DAVID B. Annnns, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and Improved Cable Grip, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved cablegrip for cars for the purpose of gripping the cable of cable-roads, and which grip can easily be raised out of the way when necessary.

The invention consists in arrangements of parts and details and combinations of the same, as will be fully'set forth hereinafter and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side view of my improved cable-grip. Fig. 2is afront view of the same. Fig. 3 is a detail view.

A flat bar, A, projects downward from the car-floor B, through the top slot, G, of the tunnel or trough O, in Which the cable D runs.

The bar A is connected by a chain, E, or otherwise Wlbh a groove-edged quadrant, E, on a shaft, F, journaled on the car-floor and having an upwardly-projecting lever, G.

An arm, 1, projects upward from the bar A, and through a nut on the end of the said arm I a screw, H, passes, having a hand wheel, J, onits upper end, and having itslower end swiveled in the upper end of a rod, K, guided in the car-floor and passing downward in front of the edge of the bar A.

On the lower end of the rod K a cross-piece, L, is secured, having a slot, M, into which pins N pass, projecting from the upper end parts of two gripping-levers, O, which are pivoted to the edge of the bar A at the bottom, and have gripping-jaws P below the pivot, from which jaws lugs Q project downward and from each other.

Guidelugs R project downward and outward from the lower end of the bar A, and an anti-friction roller, S, is journaled on the bot tom edge of the bar A to prevent thelower edge of said bar from sliding on the cable, thus greatly reducing friction.

The operation is as follows: To grip the cable, the screw H is turned to move the rod K upward, whereby the jaws P are pressed firmly against the cable. To release the cable, the rod K is moved downward. The lugs Q guide the cableD in between the j aws P. hen the car arrives at a cable-crossing, the cable D is released and the lever G swung down in the direction of the arrow a, whereby the bar A is raised by the chain E. When the bar A is lowered, the lugs R guide the cable to the lower edge of the said bar.

The grip operates rapidly and grips the cale firmly.

Instead of providing the piece L with the slot M, it may be grooved for receiving the pins N on the upper ends of the levers 0.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a cable-grip, the combination, with the bar A, of the grippinglevcrs O, the rod K, the slotted or grooved piece L, and the screw H, for operating the rod K, substantially as herein shown and described.

2. In a cable-grip, the combination, with the bar A, of the gripping-levers O, pivoted to the same, mechanism for operating said levers, the chain E, the shaft F, the quadrant E, and the lever G, substantially as herein shown and described.

3. In a eablegrip, the combination, with the bar A, of cable-gripping levers pivoted to the same, the guide-lugs 'R, and the roller S on the lower end of the said bar A, substan' tially as herein shown and described.

DAVID B. ANDERS.
